WARNING: INSTRUMENT DAMAGE
Although the OneExpert DSL OneExpert DSL is designed to
measure hazardous voltage, it is designed to do so on telecom
circuits, not power mains. Hazardous voltages may be on the
power lines. 220 mains (RMS) are equivalent to 308 peak. Con-
necting to these circuits may result in damage to equipment or
serious injury.

DC voltage

You measure DC volts to:
• detect and measure CO/exchange battery voltage.
• detect crossed battery conditions.
To measure DC volts, remove the line battery and measure Tip (A) and
Ring (B) to ground. It should be < 3.0 volts; anything else indicates crossed
battery that inhibits digital signals.
Table 37 describes the DC voltage result.
